Abstract
A quasireentrant superconducting transition in high-resistance states of a Zn-Sb alloy has been studied as a function of the transport curre nt. The current-voltage characteristics of the test sample have voltag e steps and a hysteresis. The maximum Josephson current decreases with decreasing temperature. There is a crossover from a Josephson charact eristic to a tunneling characteristic when this current is exceeded.
